Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Embodiment 1

[0028] Please refer to Figures 1-5 As shown, the present utility model is a groundwater water sample investigation and sampling device, including a support plate 1. Buoyancy seats 102 are symmetrically arranged on both sides of the support plate 1, and the two groups of buoyancy seats 102 are respectively fixed to the support plate 1 through two groups of connecting plates 101; in an implementation manner of this embodiment, the buoyancy seat 102 is composed of a floating airbag or buoyancy foam for supporting the support plate 1 to float on the water surface;

[0029] It also includes a sampling cylinder 3. The sampling cylinder 3 is connected to a sling mechanism arranged on the support plate 1, and the sling mechanism is used to drive the sampling cylinder 3 to rise and fall in the water; specifically, when sampling groundwater in this embodiment, first place the support plate 1 on the water surface to be sampled, and then drive the sampling cylinder 3 to descend in the water through the sling mechanism. When it descends to the position to be sampled, sampling can be carried out through the sampling cylinder 3;

[0030] Two groups of water inlet holes 304 are symmetrically formed in the cylinder wall of the sampling cylinder 3. Among them, a sealing mechanism is further provided on the sampling cylinder 3 for sealing the water inlet holes 304. It can be explained that in the initial state, the sealing mechanism is in a state of sealing the water inlet holes 304. When the sling mechanism drives the sampling cylinder 3 to descend to the sampling position in the water for sampling, the sealing mechanism loses the seal of the water inlet holes 304, so that water can enter the sampling cylinder 3 through the water inlet holes 304, and finally the sampling cylinder 3 can be lifted out by the sling mechanism. By setting the sealing mechanism in this embodiment, groundwater at different depths can be sampled, thereby improving the detection accuracy of groundwater.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, please refer to Figures 1-5 , the sling mechanism includes wire winding wheels 203 symmetrically and rotatably arranged at the bottom of the support plate 1. The two groups of wire winding wheels 203 are fixed by a limiting plate 204. Ropes 202 are wound around both sides of the wire winding wheels 203. Among them, supports 303 are symmetrically and fixedly arranged on the outer wall of the sampling cylinder 3. The supports 303 are fixed to the ropes 202, and the wire winding wheels 203 are connected to a rotating part that drives their rotation. It can be explained that when adjusting the height of the sampling cylinder 3, the wire winding wheels 203 are driven to rotate by the rotating part. During the rotation of the wire winding wheels 203, the effects of winding and unwinding the ropes are realized, thereby driving the sampling cylinder 3 to lift and lower.

[0033] As a further solution of this embodiment, the rotating part includes a driving motor 2 fixedly arranged on the support plate 1. A through groove 103 is formed in the support plate 1. Among them, the driving end of the driving motor 2 is connected to the wire winding wheel 203 through a pulley mechanism 201 and penetrates through the through groove 103. It can be explained that during the process of the wire winding wheels 203 taking in and paying out the ropes, when the driving motor 2 is started, the driving motor 2 can drive the wire winding wheels 203 to rotate through the pulley mechanism 201.

[0034] Furthermore, the bottom end of the sampling cylinder 3 is set as a conical structure. Among them, the bottom of the sampling cylinder 3 is fixed to a counterweight 302 through a pull rope 301. It can be explained that in this embodiment, by setting the counterweight 302 at the bottom of the sampling cylinder 3, the sampling cylinder 3 can stably descend to the corresponding height in the water.

[0035] The sealing mechanism includes a sealing cylinder 4 sleeved on the sampling cylinder 3. Two groups of through holes 401 are symmetrically and correspondingly formed on the cylinder wall of the sealing cylinder 4. Two groups of baffles 402 extending towards both sides are symmetrically and fixedly arranged on the cylinder wall of the sealing cylinder 4. Circular grooves 403 for passing through the rope 202 are formed on the baffles 402. Among them, an annular protrusion 305 is fixedly arranged at the top of the sampling cylinder 3, and an annular seat 306 that cooperates with and is clamped to the annular protrusion 305 is fixedly arranged at the bottom of the sealing cylinder 4. It can be explained that when the sling mechanism drives the sampling cylinder 3 to descend, due to the arrangement of the baffles 402, water acts on the lower surface of the baffles 402, causing the baffles 402 and the sealing cylinder 4 to move to the top of the sampling cylinder 3 under the impact of water. The cooperation between the annular protrusion 305 and the annular seat 306 can prevent the sealing cylinder 4 from separating from the sampling cylinder 3.

[0036] Correspondingly, when the sampling cylinder 3 reaches the underwater sampling position, the sling mechanism drives the sampling cylinder 3 to rise. Water acts on the upper surface of the baffles 402, causing the baffles 402 and the sealing cylinder 4 to move towards the bottom under the impact of water. When moving to the limit position, the through holes 401 coincide with the water inlet holes 304, and then water enters the sampling cylinder 3 through the through holes 401 and the water inlet holes 304, achieving the effect of water sampling.

[0037] In addition, a telescopic spring 307 is further arranged between the baffle 402 and the support 303. The telescopic spring 307 is sleeved on the rope 202. One end of the telescopic spring 307 is fixed to the baffle 402, and the other end is fixed to the support 303. It can be explained that in this embodiment, the telescopic spring 307 is arranged to support the sealing cylinder 4. When the sealing cylinder 4 moves towards the bottom, after the subsequent sampling is completed, the telescopic spring 307 can drive it to reset.

[0038] The working principle of the present utility model: First, place the support plate 1 on the water surface to be sampled. In the initial state, the sealing mechanism is in a state of sealing the water inlet hole 304. When the sling mechanism drives the sampling cylinder 3 to descend, due to the arrangement of the baffle 402, water acts on the lower surface of the baffle 402, causing the baffle 402 and the sealing cylinder 4 to move to the top of the sampling cylinder 3 under the impact of water. The cooperation between the annular protrusion 305 and the annular seat 306 can prevent the sealing cylinder 4 from separating from the sampling cylinder 3.

[0039] Correspondingly, when the sampling cylinder 3 reaches the underwater sampling position, the sling mechanism drives the sampling cylinder 3 to rise. Water acts on the upper surface of the baffle 402, causing the baffle 402 and the sealing cylinder 4 to move towards the bottom under the impact of water. When moving to the limit position, the through holes 401 coincide with the water inlet holes 304, and then water enters the sampling cylinder 3 through the through holes 401 and the water inlet holes 304, achieving the effect of water sampling.
